The McKinley Mitt provides a great combination of insulation and breathability for active mountain sports enthusiasts. This 100% waterproof glove has a waterproof breathable eVent insert that actually allows perspiration to actively evaporate without first soaking into the waterproof membrane. Combining this with 100g of lightweight moisture wicking Thermolite Active insulation gives you a mountain glove with great dexterity that keeps your hands dry from the inside and out. The entire palm, fingers and thumb are protected by Goatskin leather to protect your gloves against the grip of your poles or hours on the rope.
